Gotta prevent panic in stockholders is the main priority of a CEO in publicly traded companies. They only concern themselves with the well being of their employees as much as how it affects the stock price.
Because they risk getting punished by angry shareholders and risk lawsuits and risk losing customers if they deviate from the corporate speak to say anything substantial.
But why is every ceo feels obligated to use this kind of meaningless corpo speak in these emails? "Macro Headwinds", "full responsibility"?
